[0028] As shown in Figures 1 to 10 The present embodiment discloses a water inlet module, which comprises a water inlet valve 1 and a three-way valve 2. The water inlet valve 1 comprises a cold water inlet 11, a first mounting cavity 12, a cold water plate heat exchanger inlet 13 and a hot water plate heat exchanger outlet 14. The cold water plate heat exchanger inlet 13 and the hot water plate heat exchanger outlet 14 are connected with a plate heat exchanger 300 respectively. The cold water inlet 11, the first mounting cavity 12 and the cold water plate heat exchanger inlet 13 are communicated. A flow sensor 5 is mounted in the first mounting cavity 12. The flow sensor 5 is a prior art, and its specific structure is not described in the present specification. A first channel 15 is arranged in the water inlet valve 1. The cold water inlet 11 and the first channel 15 are communicated through the flow sensor 5. The first channel 15 is communicated with the cold water plate heat exchanger inlet 13. A second channel 16 arranged transversely is further arranged in the water inlet valve 1. One end of the second channel 16 is communicated with the first channel 15, and the other end is communicated with the cold water plate heat exchanger inlet 13. External cold water (tap water) enters the cold water inlet 11, and then passes through the first mounting cavity 12, the flow sensor 5, the first channel 15, the second channel 16 and the cold water plate heat exchanger inlet 13 in sequence, and finally enters the plate heat exchanger 300 to perform heat exchange.

[0029] The axis of the cold water inlet 11 is arranged in dislocation with the axis of the first mounting cavity 12. The first mounting cavity 12 is arranged outwardly as a whole. By dislocation arrangement, space is left for the characteristics of the first channel 15, so as to realize the communication of the first mounting cavity 12 and the cold water plate heat exchanger inlet 13. The structure is simple and reasonable in design.

[0030] As shown in Figure 5 and Figure 6As shown, the three-way valve 2 includes a heating return water interface 21, a second installation cavity 22, and a water pump interface 24, the three-way motor 6 is installed in the second installation cavity 22, the heating return water interface 21 and the water pump interface 24 are communicated or blocked through the three-way motor 6, the hot water plate heat exchanger outlet 14 and the water pump interface 24 are communicated or blocked through the three-way motor 6, and the water pump interface 24 can be connected with a water pump. Specifically, the water inlet valve 1 includes a first interface 17, the three-way valve 2 includes a second interface 23, the first interface 17 is connected with the second interface 23, the first interface 17 is inserted into the second interface 23, and the outer wall of the first interface 17 is sealingly matched with the inner wall of the second interface 23. The three-way motor 6 includes a sealing end 62 which can move up and down, the second installation cavity 22 is divided into a first cavity 221 and a second cavity 222 through the sealing end 62, the hot water plate heat exchanger outlet 14, the first interface 17 and the first cavity 221 are communicated, the first cavity 221 and the water pump interface 24 are communicated or blocked through the sealing end 62, and the second cavity 222 and the heating return water interface 21 are communicated or blocked through the sealing end 62.

[0031] The up and down movement of the sealing end 62 is controlled by the three-way motor 6, which is a prior art, so as to switch the pipeline communicated with the water pump interface 24. When the heating return water interface 21 and the water pump interface 24 are blocked, the hot water in the plate heat exchanger 300 which is cooled by heat exchange can enter the water inlet valve 1 from the hot water plate heat exchanger outlet 14, pass through the first interface 17 and the first cavity 221, and flow out from the water pump interface 24 after passing through the sealing end 62, and is transported to a boiler (not shown in the figure) through the water pump at the water pump interface 24 for heating again. When the heating return water interface 21 and the water pump interface 24 are communicated, the hot water cooled by the floor heating (not shown in the figure) enters the second cavity 222 from the heating return water interface 21, and then flows out from the water pump interface 24. It can be seen that the three-way motor 6 is installed in the water inlet module, and the three-way motor 6 is used to switch the hot water pipelines after being cooled by the plate heat exchanger 300 and the floor heating, which effectively avoids the direct contact of the sealing end 62 of the three-way motor 6 with the hot water, is conducive to improving the service life of the three-way motor 6, reducing the probability of deformation of the sealing end 62 due to heat, and effectively reducing the scaling at the sealing end 62, thereby improving the quality of the wall-hanging stove product.

[0032] As Figure 6As shown, the second interface 23 is provided with a mounting groove 26, and a one-way valve 7 is mounted in the mounting groove 26. The one-way valve 7 is a prior art, and its specific structure is not described herein. The first interface 17 and the second cavity 222 are in one-way communication through the one-way valve 7, and the communication direction is from the first interface 17 to the second cavity 222. A third channel 28 is arranged between the mounting groove 26 and the inner wall of the second interface 23. The first interface 17, the third channel 28 and the first cavity 221 are in communication. The three-way motor 6 includes an inner liner 61, and the sealing end 62 can move up and down to block the lower part of the inner liner 61 or separate from the inner liner 61.
